The present invention relates to a crane jib transition structure, mainly including a jib section, a transition section and a supporting structure, wherein, said jib section matches with said transition section, and they fixedly connect to each other, the upper end of said supporting structure fixedly connects to the upper end of the side of said jib section, the bottom end of said supporting structure fixedly connects to the bottom end of the corresponding side of the transition section, the middle part of said supporting structure fixedly connects to the connection point between the side of jib section and the corresponding side of transition section. Therefore, the crane jib transition structure of the present invention can not only achieve the strength of a crane jib transition structure, but also achieve the strength and the overall stability of a crane jib, by using a supporting structure connecting to between the crane jib section and transition section, which have simpler structure, easier installation, lower production cost and can be widely used in various types of cranes. |
